To all whom it may concern: such displacement is at once resisted by the Be it known that I, ANTON OOHSNER, of engagement of the walls of the sockets 6 with New Haven, in the county of New Haven and the exterior walls of the hubs 7, 8, and 9, so State of Connecticut, have invented a new that if the screws should work loose the cover 5 5 Improvementin Coach-Latches; andIdo herewill be still held against lateral play. This by declare the following, when taken in conis an important advantage, as I scarcely need nection with the accompanying drawings and to explain that coach-latches are subjected the letters of reference marked thereon, to be to very severe usage, whereby they are so afull, clear, and exact description of thesame, racked that their parts work loose if every to and which said drawings constitute part of precaution is not taken to resist racking this specification, and represent, instrain. Of course I do not limit myself to Figure 1, a view in inside elevation of a using three enlargements containing sockets coach-latch constructed in accordance with in conjunction with three threaded hubs, as my invention; Fig. 2, a view of the casing of the number and location of such socketed en- 15 the latch with the cover and the working parts largements and hubs may be varied as deof the latch removed; Fig. 3, a reverse plan sired. view of the cover; Fig. 4, a sectional view of As herein shown, the latch is provided with the latch on the line a b of Fig. 1; Fig. 5, an a handle-lever 14:, secured in place by means enlarged broken section showing manner of of a screw-stud l5, and employed to operate 2o securing the cover to the casing. the heavy bolt 16, provided witha mainspring My invention relates to an improvement in 17.
